China News Service, Hangzhou, April 12th: "Post-90s" astronauts of Zhejiang University: Be the "back wave" of today and be the "front wave" of the younger generation

Research and development, testing, business trips, popular science.
This is the daily work of Sun Shujian, a postdoctoral fellow at the School of Aeronautics and Astronautics of Zhejiang University.
As a "post-90s" astronaut, he has many goals: the shortest one is to complete the launch target of 15 satellites this year, and the longer one is to make China's microsatellite technology lead the world and bring aerospace knowledge to all walks of life .
But what has been consistent is a simple belief: to overcome difficulties a little more.
"We will all become 'front waves' in the end." Sun Shujian said that the aerospace industry needs to be passed down from generation to generation. This generation will overcome the pressure and difficulties first, and the next generation will follow.
April 12 is World Space Day. The reporter visited the story behind the "post-90s" astronaut.
The moment the call was connected, the young astronaut had been on a business trip in Xi'an, Shaanxi Province for nearly a month.
On March 30, Tianping 2 B and C satellites, in which he served as the overall chief designer and the chief designer of the control system, were loaded with the Long March 11 carrier rocket and successfully entered the predetermined orbit.
These are two microsatellites weighing kilograms, mainly used for ground radar equipment calibration and RCS measurement, to provide support for ground optical equipment imaging experiments and low-orbit space environment detection and monitoring experiments, and for atmospheric space environment measurement and orbit prediction models. Amendment to provide services.

In fact, since joining the Microsatellite Research Center of Zhejiang University in 2013, Sun Shujian has participated in the development and demonstration of 20 satellites.
The Pixing-2 satellite of Zhejiang University is the first full-satellite development mission that he has fully participated in.
According to the requirements, the development cycle of Pixing 2 is only 11 months.
Previously, a ground equipment with the same effect took 13 years to design alone.
He remembers when the entire team was at full capacity during the development phase.
The entire team of 82 teachers and students worked 335 days a year, and the total number of overnight stays reached 2,106.
I was often called back to the laboratory by a phone call in the early morning, and it was a common practice to stay overnight. The longest continuous test lasted for four days and four nights.
"Unlike other industries, the aerospace industry is a team project, and there is no individual hero." Sun Shujian said that many problems need to be solved by the team. "One person's backwardness may cause the entire team to stand still or go backwards."
It is also because of his exposure to this project that he understands that he must have full enthusiasm in the aerospace industry. Many problems cannot be solved simply by spending time, and he must continue to study them.
But after the difficulties, the joy of the satellite successfully entering the predetermined orbit is beyond the experience of ordinary people.
"The moment the rocket was launched, the teachers and students of the team were so excited that their eyes filled with tears, and they all said that it was like sending their children into space." Sun Shujian said.
Now, in his circle of friends, you can also see the record of two children as an "old father".
On March 30, he wrote: The vast space remembers you, two little guys, refuel in orbit; on April 1, he released a black-and-white photo of the earth, which is the infrared image of the satellite after it entered orbit. The first photo taken by the camera.
The words are full of "old father" comfort: when you are still worried about its state, the satellite will always give you a little surprise.
From explorer to adherent, Sun Shujian not only forges ahead in technical research, but also keeps pace in aerospace science.
In 2016, he was invited by a non-profit organization to start a live broadcast of aerospace science popularization on the Internet.
"Nearly 20 science popularization activities are held every year to explain basic knowledge to children in remote mountainous areas." He said that aerospace science popularization is a career worthy of lifelong practice.
Now more and more "post-90s" people are joining the aerospace industry, and the media frequently compare these young people to "post-waves".
But in Sun Shujian's view, they will eventually become "front waves".
He said that the research and development of microsatellites still has a long way to go for China.
They have to be the "back wave" of today and the "front wave" of the next generation.
